In FIG. 3, an aluminum oxide (Al 2 O 3 ) twisted yarn 4 is wound around a core metal 3 at a predetermined pitch (for example, 5 mm, 10 mm, etc.). Then, a predetermined width (for example, 3
mm, 8 mm), and a water-soluble film 5 having a thickness of 80 μm is wound. Here, this water-soluble film includes, for example, one made of polyvinyl alcohol resin, but is not limited to this. Further, as shown in FIG. 2, a unidirectionally aligned carbon fiber prepreg 6 impregnated with an epoxy resin around the outer periphery of the alumina oxide twisted yarn 4 and the water-soluble film 5 is wound in the circumferential direction, and further impregnated with the epoxy resin on the outer periphery. The unidirectionally aligned carbon fiber prepreg 7 is wound in the axial direction, and these are wound a plurality of times. afterwards,
A forming tape (not shown) is wrapped around the outermost periphery and heated and baked.
